1. What Changed in 2026 and What Did Not
The biggest mistake many investors are making is assuming that 2026 created an entirely new tax regime only for Post Office schemes. That is not the most accurate way to read the law.
What actually changed from 1 April 2026 is the form and reporting framework under the new Income-tax Act, 2025 and Income-tax Rules, 2026. In practical terms, the shift matters because old compliance tools have been renumbered, declarations have become more system-driven, and reporting trails are now easier to map across PAN, TDS reporting, SFT reporting and AIS.
| Issue | Position from 1 April 2026 | Practical meaning |
|---|---|---|
| Old Form 60 / 61 structure | Replaced in the new form architecture by Form 97 / 98 | Non-PAN transactions are now governed by the new forms framework |
| Forms 15G and 15H | Replaced by Form 121 | Eligible investors now use one unified declaration form |
| Tracking of no-TDS declarations | UIN-based reporting introduced for Form 121 | Each accepted declaration becomes easier to trace |
| Visibility of reportable activity | SFT and AIS continue to matter heavily | Large deposits, time deposits and interest trails can surface in tax systems |
2. PAN, Non-PAN Declarations and Post Office KYC
At the ground level, PAN remains the central tax identity. India Post’s savings scheme guidance has long required KYC discipline, and its published investor guidance states that PAN number or Form 60/61 is mandatory for opening new accounts and updating existing account records. In 2026, the tax form architecture underneath that position has changed, even where some legacy Post Office guidance still refers to old form numbers.
Separately, the Income Tax Department’s PAN guidance continues to emphasize that quoting PAN or Aadhaar becomes relevant in specified financial transactions, including certain high-value cash deposits and withdrawals through post office accounts.
Where PAN matters most in practice
- Opening or regularising Post Office account KYC
- Specified non-PAN transactions now covered by Form 97 rules
- Submitting Form 121 for no-TDS declaration, where PAN is mandatory
- Reconciling financial trails visible to the tax department through AIS and SFT
3. Form 97 and Form 98 Explained Correctly
This is one area where online summaries are often wrong. Under the Income-tax Rules, 2026, Form 97 is the new declaration form for a person without PAN who enters into a specified transaction covered by the rules. The official draft form specifically includes investment in time deposit as one of the transaction categories.
However, Form 98 is not an investor declaration form. It is the statement containing particulars of declarations received in Form 97. In other words, Form 98 is part of the reporting layer for the receiving institution or reporting person, not a second form that a normal investor fills just because he or she invests in a Post Office scheme.
Practical example
Suppose Meena wants to invest in a Post Office Time Deposit but does not yet have PAN. Under the new 2026 form structure, the relevant non-PAN declaration framework is Form 97, not the old Form 60 numbering. But that does not mean every non-PAN case becomes risk-free. If KYC, thresholds or other reporting rules are triggered, the transaction can still fall into a more visible compliance bucket.
4. Form 121 Replaces Form 15G and Form 15H from 1 April 2026
This is the most important confirmed 2026 change for Post Office interest-related TDS compliance. The Income Tax Department’s official Form 121 guidance and FAQ documents state that Form 121 has replaced the earlier Forms 15G and 15H.
Form 121 is a declaration under section 393(6) of the Income-tax Act, 2025. It is used where eligible taxpayers declare that tax on their estimated total income for the tax year will be nil, so specified income can be received without TDS.
Why this matters for Post Office investors
The official guidance note specifically includes interest other than interest on securities paid by bank, co-operative bank or post office within the scope of Form 121. That makes this highly relevant for investors who rely on Post Office interest income and want to avoid unnecessary TDS where they are genuinely eligible.
Key rules for Form 121
- It applies only if the taxpayer is eligible under the rules
- PAN must be valid and operative
- It should ideally be submitted before income is credited or paid
- It must be given separately to each payer
- It is not a blanket immunity form; false or wrong declarations can create problems later
Practical example
Suppose Mrs. Shah is a senior citizen whose estimated total tax liability for the tax year is nil, even after considering her Post Office interest and deductions. Before 1 April 2026, she would typically think in terms of Form 15H. From 1 April 2026, the declaration route is Form 121, provided she actually satisfies the eligibility conditions.
5. What the 26-Character UIN Really Tracks
Another commonly mis-stated point is the 26-digit or 26-character UIN. Officially, the new system uses a 26-character alphanumeric UIN for each Form 121 declaration received by the payer. This was laid down in Notification No. 01/CPC(TDS)/2026 dated 28 March 2026.
That means the UIN is not a universal number for every Post Office account, every NSC purchase or every deposit slip. It is specifically a tracking identifier for accepted Form 121 declarations.
The official FAQ explains that the UIN contains three components:
- A running serial number
- The relevant tax year
- The payer’s TAN
This matters because once a declaration is accepted and reported, the department has a cleaner audit trail connecting the declarant, the payer and the no-TDS event.
6. SFT and AIS: This Is Where Visibility Becomes Real
If you want to understand why Post Office compliance matters more now, look beyond just PAN and forms. The deeper reason is the reporting ecosystem.
The Income Tax Department’s official SFT material confirms that the Post Master General is one of the specified reporting persons for certain financial transactions. The department’s AIS material also confirms that SFT information can appear in a taxpayer’s Annual Information Statement.
| Transaction / reporting area | Official reporting position | Practical compliance impact |
|---|---|---|
| Cash deposits in non-current, non-time-deposit accounts | Reportable under SFT if aggregate amount is ₹10 lakh or more in a financial year | Large cash movement in savings-type Post Office accounts can become visible |
| Time deposits | Reportable under SFT if aggregate amount is ₹10 lakh or more in a financial year | Splitting deposits does not necessarily prevent annual aggregation |
| Interest reporting | Interest reporting by Post Master General is part of the SFT architecture, subject to exclusions for exempt categories such as PPF | Interest-linked tax mismatches become easier to identify |
| AIS visibility | AIS contains SFT information uploaded to the tax system | ITR figures should be reconciled with AIS before filing |
Practical example
Suppose a taxpayer makes multiple time deposits in the Post Office during the year and the aggregate crosses the relevant SFT threshold. Even if the taxpayer mentally treats each investment as separate, the reporting framework may look at the year-wise aggregate. If the same taxpayer later files a return with low disclosed income and no credible source narrative, that mismatch can become difficult to defend.
7. What This Means for RD, MIS, NSC and Time Deposit Investors
Different Post Office schemes do not all behave identically from a tax perspective, but the compliance lessons are increasingly common across schemes.
Recurring Deposit (RD)
RD investors should not assume that because the product feels “small savings” in nature, it is invisible. PAN-linked KYC, interest taxability analysis and AIS reconciliation still matter.
Monthly Income Scheme (MIS)
MIS investors should pay special attention to actual interest income reporting, especially where Form 121 is being considered. A declaration should never be filed casually without checking the total income position for the tax year.
National Savings Certificate (NSC)
NSC investors often focus only on deduction planning. In practice, tax treatment, accrual working and documentary support should be kept clean year by year, especially if the investment pattern is large or repeated.
Time Deposit (TD)
Time Deposits are especially important because they sit close to the intersection of non-PAN declaration rules, PAN quoting discipline and SFT time-deposit reporting thresholds.
8. Common Mistakes Taxpayers Should Avoid
- Assuming Form 121 can be filed without PAN
- Thinking Form 98 is a personal investor form
- Believing the 26-character UIN applies to every account rather than every Form 121 declaration
- Ignoring AIS while filing the return
- Using a no-TDS declaration without checking total estimated tax liability first
- Splitting investments across dates and assuming annual reporting will not aggregate them
- Not preserving deposit receipts, passbooks, declaration acknowledgements and interest workings
9. Practical Compliance Checklist
Before investing further in Post Office schemes during Tax Year 2026-27, use this checklist:
- Ensure PAN and KYC details in your Post Office records are updated and operative
- If PAN is unavailable, understand whether Form 97 is actually relevant to your transaction type
- If you want non-deduction of tax on eligible interest income, review Form 121 carefully before filing it
- Submit Form 121 before credit or payment, preferably at the start of the tax year
- Track yearly aggregates, not just individual deposits
- Download and review AIS before filing your ITR
- Keep documentary proof of source of funds, investment, interest, maturity and declaration filings
10. Key Timing Points That Matter More Than Viral Deadlines
Some online posts mention broad dates without context. The official material gives a more useful compliance picture:
- Form 121 should ideally be furnished before income is credited or paid, and preferably at the beginning of the tax year
- The payer must upload details of declarations received in Part B of Form 121 on or before the 7th of the month following the quarter
- SFT reporting in Form 61A is generally due on or before 31 May immediately following the financial year in which the transaction was recorded
For individual taxpayers, the smarter focus is not memorising random dates from social media. It is making sure declarations are timely, records are maintained and the return is filed only after AIS reconciliation.

12. Frequently Asked Questions
Is PAN compulsory for every Post Office transaction from 2026?
No. That statement is too broad. PAN-centric compliance now matters strongly through KYC, specified transaction rules, declaration rules and reporting systems, but the exact requirement depends on the nature and scale of the transaction.
Can a person without PAN still invest in a Post Office Time Deposit?
The new non-PAN declaration framework is governed by Form 97 for specified transactions, and the official draft form includes investment in time deposit. But that does not override all KYC, threshold and reporting requirements.
Has Form 15G or Form 15H been replaced?
Yes. From 1 April 2026, Form 121 is the unified declaration for eligible taxpayers seeking no deduction of tax on specified incomes.
Can Form 121 be filed without PAN?
No. The official guidance makes it clear that valid and operative PAN is mandatory for Form 121.
Is Form 98 to be submitted by every investor?
No. Form 98 is a reporting statement containing particulars of declarations received in Form 97. It is not the same as a personal investor declaration form.
Does every Post Office account now get a 26-character UIN?
No. The 26-character UIN is for each Form 121 declaration allotted by the payer, not for every Post Office account or every individual transaction.
Will Post Office transactions appear in AIS?
Depending on the nature of the transaction and the applicable reporting rules, Post Office-related information can feed into SFT reporting and then become visible in AIS.
What is the biggest compliance risk for investors?
The biggest practical risk is mismatch: your Post Office investment pattern, interest trail, declarations and ITR should tell the same story. If they do not, future notices become harder to answer.
13. Final Professional Takeaway
Post Office investing is still a valid and widely used savings route. What has changed is the compliance expectation around it. As of 1 May 2026, the safest professional reading is this: Post Office investments are no longer low-visibility from a tax-reporting perspective.
The winning approach is not panic. It is precision. Keep PAN and KYC clean. Understand when Form 97 is relevant. Use Form 121 only when legally eligible. Reconcile AIS. Preserve records. When the paperwork matches the money trail, scrutiny risk falls sharply.
